A term commonly used for going stupid smack. It specifically refers to an extreme level of savageness when engaging in flirtation with the opposite sex. When going gusto one would go smack at everything in whatever location they are in while also saying "off the wall things." The term has started to become popular in the DMV area but the term originated in North Carolina.
